The Hornady Superformance 7mm-08 Rem. 139 gr. CX SPF delivers long-range, hunting-ready ballistics from Hornady's Superformance series, pairing the CX (Copper Alloy eXpanding) bullet with the Superformance load to push 139-grain projectiles to a muzzle velocity around 2910 fps and muzzle energy near 2613 ft-lbs, giving hunters flatter trajectories, stronger terminal performance and reliable expansion on medium to large game; chambered for 7mm-08 Remington and built on brass casings with a copper-colored projectile, this load is made in the United States and carries ORM-D shipping designation with HazAir considerations for transport, so range safety officers and outfitters appreciate the consistent velocities and point-of-impact repeatability the SPF line is known for. If you run mountain stalks, wooded stands, or precision field shots, the CX bullets copper alloy construction and controlled expansion deliver deep penetration without the fragmentation concerns of some designs, while the Superformance series higher velocity profile extends effective range and flattens holdover, making it a go-to choice for hunters who demand reliable terminal performance from a 7mm-08 Rem cartridge.
